SPEGIFIOATION formingpart of Letters Patent No. 669,616, dated March 12, 1901.

Application filed August t, 1900. Serial No. 25.944. (No model) To aZZ whom, it may concern:

Be it known that I, ROBERT BURGESS, J12, a subject of the Queen of Great Britain, residing at Oongleton, county of Chester, England, have invented a new and useful Improvement in Vignetting-Frames for Photography, of which the following is a specification.

My invention has for its object improvements in and relating to vignetting-frames for photography by which I am enabled to easily and quickly change or vary the size of the vignetter and at the same time produce a superior vignette than is possible with the present form of vignetter.

In order that my invention may be more clearly understood and easily carried into practical effect, I have appended hereunto a sheet of drawings, upon which I have illustrated my improved vignetting-frame.

Figure l is a front view of my vignettingframe fixed in position on the usual printing frame. Fig. 2 is a side view of Fig. 1. Fig. 8 is a part sectional side view of Fig. 1. Fig. 4 is a plan view of the vignetter.

In carrying my invention into practice I form the frame F of my vignetting apparatus from metal, wood, cardboard, or other suitable material, either in one piece or in two or more parts, the upper edges f being flanged inwardly and the lower edges f preferably flanged outwardly, as clearly shown at Fig. 1. The outwardly-turned flanges f at either end of the frame are preferably enlarged or project farther outward than the side flanges, and cut or formed in these end flanges f are the radial slots f through each of which the screws f or their equivalents pass for ad justably fixing or attaching the frame F to the usual printing-frame A. By this means the vignetting-frame may be adjusted to suit the particular position of the negative on the printing-frame in an easy and simple manner.

The vignetter V is made from a length of flexible materialsuch, for instance, as the textile material used for binding books, which I find very suitable for the purpose-and at certain distances apart in this material I cut a number of holes or openings 1; of various sizes and 0f the required shape, the number of holesor openings depending on the length of the material used. I find that a piece of material of sufficient length to enable six different-sized holes to be cut therein and of such a width as to fit into the frame F answers the purpose very well; but I do not limit myself to this number of holes, as there may be more or less. This vignetter or length of flexible material V is then attached at either end to the rollers R, mounted in bearings near the ends of the sides of the frame F under the flanges f, the vignetter preferably fitting close or nearly close to the under side of these flanges. One of the ends of each of these rollers or spindles R protrudes through the side of the frame, and on each end are fixed the ratchet-wheel W and handle H or equivalent, so that by turning either one or both of these handles the vignet-ter V is wound off one roller onto the other, thus enabling the size of the hole or opening to be easily and quickly changed and the vi gnettin g varied when required. Pivoted to the side of the frame are pawls P, which take into the teeth of the ratchet-wheels, so that when the vignetter is once set it can be securely held in that position by these pawls; but if it is desired to change the vignette the pawls are moved out of contact with the teeth of the ratchet-wheels, thus allowing the handle or handles to be turned. These pawls and ratchet-Wheels also enable the vignetter to be tightly stretched.

Pivoted to opposite sides of the frame F, under the flanges f", are the arms J, which bear upon the vignetter V, their opposite ends fitting into catches or their equivalents, as clearly shown at Figs. 1 and 3. These arms are provided for the purpose of pressing or holding the vignetter nearer or closer to the negative when it is desired to further limit or curtail the portions being printed, and when not in use they can be moved on their pivots and laid under the flanges By the use of a vignetting frame or apparatus made according to my invention I am enabled to produce with the one frame a 11 umher of different vignettes, thus obviating the necessity of a separate frame for each vignetter.

What I claim is- 1. In combination with a printing-frame, a

' ing said rollers against movement when de- 10 sired.

In Witness whereof I have hereunto set my hand in presence of two Witnesses.
